Diesel engine fire pump is a kind of fire-fighting equipment that we often see and often use in our life. The diesel engine fire pump has the characteristics of good starting performance, strong overload capacity, compact internal structure, convenient maintenance, simple operation and high degree of automation. It is a very reliable fire fighting equipment.

The EDJ fire pump set is tested in the Better factory, and our company’s fire pump set needs to be tested after the assembly is completed to ensure the quality. EDJ fire pump sets are widely used in large public places, factories, firefighting and other occasions.

A multistage pump refers to a pump with two or more impellers, which can absorb and press water in stages and multiple stages, so as to lift the water to a high position, and the lift can be increased or decreased according to the needs of the pump impeller. The multistage pump can be equipped with a four-stage motor by increasing the number of impellers when the single-stage pump head needs to be equipped with a two-stage motor, which can improve the service life of the pump and reduce the noise of the unit. It is placed flat on the ground, with better stability, large flow and head, and wider application.

EDJ fire pump set is composed of electric pump, diesel pump and stabilized pressure pump. In daily use, as an auxiliary pump, the stabilized pressure pump keeps the existence of liquid (water) in the fire pipeline at all times, and the electric pump works as the main power pump in normal work. When the circuit system is burnt out due to a serious fire, the diesel pump will start instead of the electric pump within ten seconds, which will not be affected by the circuit and complete the fire fighting work. In recent years, EDJ fire pump group has gradually become the first choice of fire protection systems in various office buildings and residential buildings, and its safety

Fire pumps are mainly used for pressurized water delivery in firefighting system pipelines, and can also be used in industrial and urban water supply and drainage, high-rise building depressurized water delivery, long-distance water delivery, heating, bathrooms, boiler cold and warm water circulation pressurized air conditioning refrigeration system water delivery and equipment matching, etc.

As usual, Fire pump system include Diesel engine pump + Electric motor pump+Jockey pump. Sometime, it just include Electric pump+Jockey pump.
Its power: 1.0 to 20kw, flow: 15-300gpm, head: 3-10bar, 50/60hz. The material: Cast iron or SS, bronze impeller.

Fire pumps should be tested on a regular basis according to national and local regulations. Common testing frequencies are monthly, quarterly, annually, and five-yearly, with different tests conducted at each interval.

The DJ Fire Pump Set is a combination system consisting of a diesel engine pump and a jockey pump, designed for fire safety in the construction and industrial sectors. This system utilizes the powerful power output of the diesel engine pump, ensuring reliable operation even in the event of a power outage. The jockey pump maintains a constant water pressure, optimizing the performance of the fire suppression system. The DJ Fire Pump Set offers a reliable and efficient solution for prompt response to fire incidents, making it an essential component for protecting property and ensuring occupant safety.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.
